PROCESS OF PRODUCING LUSTROUS DESIGNS.

No Drawing.

To all whom it may concern:

Be it known that I, FRANK Bonn, a citizen of the United States, residing at Washington, in the District of Columbia, have invented certain new and useful Improvements in Processes of Producing Lustrous Designs, of which the following is a specification.

My said invention relates to a process of reproducing in pictures the natural lustre or sheen of the feathers of various birds, or

other objects, so that said pictures will not only be faithful reproductions of the natural colorings of the birds but also of the lustre of the plumage, all as will. be hereinafter more fully described and claimed.

The said process consists in covering the surface on which the picture is to be made, whether of paper, canvas, or other material, with an adhesive paste laid on carefully and thinly but rapidly and without bubbles and then immediately covering the same with gold or silver foil, or any metallic reflecting surface that may be appropriate to reproduce the lustre desired. After the paste has been covered with the metal foil and has become thoroughly dry, I then lay on a thin coat of transparent medium, or size, which, when dry, will protect the thin metal coat from erosion during the next succeeding ap- SO plications. I then dissolve in hot but not boiling water a clear, good quality of gelatine sufficient to make a thin jelly or paste. This jelly or paste is then colored or tinted with such transparent color as it may be desired to reproduce and while in fluid con dition, is spread over the surface of the foil. This coat is allowed to cool and harden.

Upon this gelatine surface may be traced or developed feather, or other design, using transparent or opaque colors, depending upon the effect desired.

lVhile I have mentioned foil as the basis of the metallic surface and in use found it most suitable for the purpose because of its convenient form for use and its light-reflecting characteristics, it will be understood, of course, that any other metallic or light-reflecting substance found suitable may be substituted therefor if preferred.

Application filed November 3, 1921.

Serial No. 512,620.

The use of the gelatine or other similar transparent material appropriately colored or tinted with transparent colors produces upon the metal foil a permanent and e'l'licient medium through which the foil reflects the light and perfectly imitates the brilliant metallic lustre characteristic of the plumage of many birds.

By this process pictures of birds (or other objects having lustrous features) may be made of permanent character in which the colorings will not only be perfectly duplicated but the brilliant lustre and sheen of the plumage as well.

Having thus fully described my said invention, what I claim as new and desire to secure by Letters Patent, is:

1. The process of producing lustre in pictures which consists in covering the surface on which the picture is to be produced with an adhesive paste, placing thereon metallic substance of the character required for the purpose, covering the same with a transpan ent protecting medium, then covering the surface with a transparent paste of the color such as it is desired to reproduce, then tracing thereon with transparent or opaque colors the designs desired.

2. The process of producing lustre on decorated surfaces which comprises covering the surface with light-reflecting substance. covering the light-reflecting substance with a transparent protecting medium, then colon ing the surface, then producing the design thereon with transparent or opaque colors.

3. The process of producing lustre on deeorated surfaces whichcomprises forming a reflecting surface, then applying a size upon the surface to protect the same from erosion, and covering the same with the colors re quired, substantially as set forth.

In witness whereof, I have hereunto set my hand and seal at lVashington, District of Columbia, this 2nd day of November, A. D. nineteen hundred and twenty-one.
